llIACl-QLIINE FOR FORMING, PRINTING, ASSEMBLING ENVELOPES.

Application filed September 30, 1921.

The present invention. relates to a. machine for forn'i'ing, printing and assembling envelopes from previously formed blanks, and while its use is not 1: trictcd to the formation, printing and as .mbling of p'lassine envelopes, it particularly adapted. for that type.

it is an object of the invention to provide for tho forn'iation, printii and assembling of envelopes of various sizes.

It is a further object of this invention to provide for the gunnning of one side flap of successive envelope blanks, the accurate folding of the side flaps over the body portion ofthe blanks, and the securing of the flaps together, the gui'nming of one end flap, the folding of this flap, and the securing of the same to the previously folded and. secured side flay s, the creasing of the other end flap, if desired, the accurate printing on the face of the envelope, and the assembling; of the completely formed and printed envelopes in predetermined numbers.

Furthermore, the invention. comprehends the feeding; of the envelope blanks, successively, to the various positions in which an operation is performed on the blanks, and the positioning of the blanks so that the side and end wings will be properly folded, and so that the printing will be aligned and positioned on the face of the envelope.

Various other objects will appear as the description of the invention progresses, and I, therefore, do not deem it necessary to onunun-ato all the objects at this time.

In the embodiment of the invention isclosod in the drawings, which is merely chosen for the purposes of illustration, and to the details of which ll do not wish to be limited, except as is necessitated by the claims, I have shown means for supporting a stack of envelope blanks, each of which blanks includes a body portion, side wings and end wings see Figure This sup porting means for the blanl s is in the form of a hopper, from which the blanks are suc- ,-essively separated and withdrawn from the bottom of the stack. The withdrawn blanks are successively carried on to a support, where they are held in position, and an adhesive applied to one edge of one of the side wings of each (see Figure 36), the adhesive applying, means being disposed laterally of the path of travel of the envelope blanks, so as not to interfere with the prog- Serial No. 504,446.

ress of the blanks through the machine. The hopper, together with the means for holding the envelope on to the support, and the means for applying the adhesive to one side wing of the envelope, are adjustable, so that envelope blanks of any size up to a predetermined limit may be operated upon.

From this position, where the blank receives the adhesive on one of its side wings, the blank passes to adjustable mechanism for folding the side wings over the body portion of the blank and one upon the other (see Figure 37), the wings being elevated prior to the arrival of the blank at the position in which the wings are folded, so that the folding means may operate upon the wings.

lirior to the folding operation and in the travel of the envelope blank from the hopper to the folding means the blank is guided, and immediately preceding the folding of the side wings the blank is positioned with respect to the folding means, so that the wings will be accurately folded and the blank with the folded side wings will be in proper position for presentation to the means for applying adhesive to the end wing and to the printing and assembling mechanism, the positioning means being adjustable to accommodate envelope blanks of various sizes.

After the side wings are folded, they are pressed together, to insure the adhesion of the wings, and the blank with these folded side wings is then fed to adjustable means fo' applying adhesive to one end wing (see Figure 39), and with which, a device which will crease the opposite end wing may be associated, if desired.

From the means for applying the adhesive and creasing the end wing of the envelope, the latter passes to means for folding and applying pressure to the end wing to insure its adhesion to the already folded and secured side wings (see Figure 41.). The envelope thus formed then passes to an assembling mechanism, lirst passing through a printing mechanism, which serves not only to print on the face of the envelopes (see Figure 40), but to feed them from the forming mechanism to the assembling mechanism.

'lvieans are provided for indicating the assembly of a predetermined number of formed and printed envelopes, and for indicating the failure of the machine to feed parent series.

an envelope from the hopper to the various parts of the machine.
